Coral reefs that survive rapid bleaching fuelled by global warming remain deeply damaged, with little prospect of full recovery, researchers said Wednesday. Sixteen years after the 1998 El Nino ravaged coral in the Indian Ocean’s Seychelles archipelago, no reefs had recovered their original growth rates and barely a third were expanding …

Huge crack in the Antarctic grows by a further six miles
It now measures more than 100 miles and only a final 12 remain before an iceberg forms. A crack in an ice shelf, known as Larsen C, in Antarctica has grown by more than six miles in the past few weeks…

Changing atmospheric conditions may contribute to stronger ocean waves in Antarctica
Over the past few years, a large fracture has grown across a large floating ice shelf on the Antarctic Peninsula. The world is watching the ice shelf, now poised to break off an iceberg the size of Delaware into the ocean…

Global sea ice is at lowest level ever recorded
It’s a new low point. The area of the world’s oceans covered by floating sea ice is the smallest recorded since satellite monitoring began in the 1970s. That means it is also probably the lowest it has been for thousands of years…

Warmer waters linked to higher levels of shellfish toxin
As the Earth warms up, you may want to lay off the shellfish: Warmer ocean waters are linked to increased — and possibly dangerous — levels of domoic acid, a toxin in shellfish and other marine animals that can make people sick, a new study finds…

Thawing Arctic is turning oceans into graveyards
Nasa researchers have found that the thicker multi-year ice, which has survived several summer melt seasons, is being rapidly replaced by thinner, more ephemeral one-year ice formed over a single winter…

New research predicts the future of coral reefs under climate change
New climate model projections of the world’s coral reefs reveal which reefs will be hit first by annual coral bleaching, an event that poses the gravest threat to one of the Earth’s most important ecosystems…

Study confirms steady warming of oceans for past 75 years
A controversial paper published two years ago that concluded there was no detectable slowdown in ocean warming over the previous 15 years – widely known as the “global warming hiatus” – has now been confirmed using independent data…

Study finds potential instability in Atlantic Ocean water circulation system
One of the world’s largest ocean circulation systems may not be as stable as today’s weather models predict, according to a new study. In fact, changes in the Atlantic Meridional Overturning Circulation (AMOC)—the same deep-water ocean current featured in the movie “The Day After Tomorrow”—could occur quite abruptly, in geologic terms, …
